Question
Transcribed Image Text:The manager of a resort hotel stated that the mean guest bill for a weekend is $600 or less. A member of the hotel's accounting staff noticed that the total charges for guest bills have been increasing in
recent months. The accountant will use a sample of future weekend guest bills to test the manager's claim.

The hypotheses Ho: µ 2 600 and H: µ < 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is greater than or equal to 600 and find
evidence to support µ < 600.
The hypotheses Ho: u < 600 and H: u > 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is less than or equal to 600 and find
evidence to support u > 600.
The hypotheses Ho: u = 600 and H: µ + 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is equal to 600 and find evidence to
support u + 600.
